Xbox could only boast they had handed over 5million Xbox Ones to shops, and not all of them would have necessarily been sold to customers.

Numbers coming out of Japan this morning showed Sony managed to shift a thumping 18.7million systems across all platforms last year, including the PS3 and Vita, while

Nintendo sold 16.31million. Coming in a distant third place was Microsoft with 11.6million console sales.

The firm was slammed by fans at last year's E3 because it focused on Xbox One being an "all-in-one" entertainment system covering things like interactive TV.

Sony concentrated on being "for the players" and all about the PS4 as a gaming system for the hardcore. It sparked whoops of cheers from the E3 crowd.

Microsoft was forced to do a series of U-turns on unpopular plans for its console, like not allowing the machine to easily take used games and forcing people to have a constant connection to the web for it to work.
